We are adding support in the existing version agnostic SQL Server MP (2017+) to monitor older versions of the server, specifically 2012 through 2016. SQL Server 2008 and R2 end of support is nearing (July 2019) so we will leave monitoring 2008 in its own MP. This is an update to the public preview we released earlier this year (release blog post). Please refer to that blog post for that release on the details of planned changes as it involves some naming changes and impacts custom MPs.

Please install and use this public preview and send us your feedback (sqlmpsfeedback@microsoft.com)! We appreciate the time and effort you spend on these previews which make the final product so much better.
